To calculate the LCM of 24 and 32 by the division method, we will divide the numbers(24, 32) by their prime factors (preferably common). The product of these divisors gives the LCM of 24 and 32.
- Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 24 and 32. Write this prime number(2) on the left of the given numbers(24 and 32), separated as per the ladder arrangement.
- Step 2: If any of the given numbers (24, 32) is a multiple of 2, divide it by 2 and write the quotient below it. Bring down any number that is not divisible by the prime number.
- Step 3: Continue the steps until only 1s are left in the last row.
The LCM of 24 and 32 is the product of all prime numbers on the left, i.e. LCM(24, 32) by division method = 2 × 2 × 2 × 2 × 2 × 3 = 96.

Example 1: Verify the relationship between GCF and LCM of 24 and 32.
Solution:
The relation between GCF and LCM of 24 and 32 is given as,
LCM(24, 32) × GCF(24, 32) = Product of 24, 32
Prime factorization of 24 and 32 is given as, 24 = (2 × 2 × 2 × 3) = 23 × 31 and 32 = (2 × 2 × 2 × 2 × 2) = 25
LCM(24, 32) = 96
GCF(24, 32) = 8
LHS = LCM(24, 32) × GCF(24, 32) = 96 × 8 = 768
RHS = Product of 24, 32 = 24 × 32 = 768
⇒ LHS = RHS = 768
Hence, verified. -
Example 2: The product of two numbers is 768. If their GCD is 8, what is their LCM?
Solution:
Given: GCD = 8
product of numbers = 768
∵ LCM × GCD = product of numbers
⇒ LCM = Product/GCD = 768/8
Therefore, the LCM is 96.
The probable combination for the given case is LCM(24, 32) = 96. -
Example 3: The GCD and LCM of two numbers are 8 and 96 respectively. If one number is 32, find the other number.
Solution:
Let the other number be b.
∵ GCD × LCM = 32 × b
⇒ b = (GCD × LCM)/32
⇒ b = (8 × 96)/32
⇒ b = 24
Therefore, the other number is 24.
